Abstract

In risky and other multiattribute choices, the process of choosing is well described by random walk or drift diffusion models in which evidence is accumulated over time to threshold. In strategic choices, level-k and cognitive hierarchy models have been offered as accounts of the choice process, in which people simulate the choice processes of their opponents or partners. We recorded the eye movements in 2 × 2 symmetric games including dominance-solvable games like prisoner's dilemma and asymmetric coordination games like stag hunt and hawk–dove. The evidence was most consistent with the accumulation of payoff differences over time: we found longer duration choices with more fixations when payoffs differences were more finely balanced, an emerging bias to gaze more at the payoffs for the action ultimately chosen, and that a simple count of transitions between payoffs—whether or not the comparison is strategically informative—was strongly associated with the final choice. The accumulator models do account for these strategic choice process measures, but the level-k and cognitive hierarchy models do not.

Description:	Data record consists of 6 data files in .csv format with an accompanying readme file. We explored the choices and eye movements made by participants in a range of symmetric 2 × 2 games. Our approach is to build statistical models, which describe the eye movements and their relation to choices. Fifty-four undergraduate and postgraduate students were recruited from Warwick University and participated for a payment of £5 plus a further payment of up to £5 contingent upon the outcome of a randomly selected game. Details on each individual data file can be found in the accompanying readme.
